请教关于RTT、LWIP在TM4C129芯片上整合的问题。

我原来用TM4C129都是裸机工程，现在想移植一个操作系统，刚开始直接下载了3.0.3版本的，发现运行到创建任务时就出现问题了，如下图所示：

后来选择了RTThread-NANO版本，直接在我的裸机工程上进行修改、添加。
修改了board.c文件，内容如下：

```c

现在的问题是  裸机情况下可以正常运行，一旦使用RTOS就停止在下图所示的函数了：

网卡初始化都是原来的函数：
```c
void ETH_Init(void)
{
        u8 i;
        uint32_t ipaddress=0,mask=0,gate=0;
        
        ROM_SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOF);
        ROM_SysCtlPeripheralEnable(SYSCTL_PERIPH_GPION);
        
        ROM_GPIOPinConfigure(GPIO_PF0_EN0LED0);
        ROM_GPIOPinConfigure(GPIO_PF4_EN0LED1);
        
        GPIOPinTypeEthernetLED(GPIO_PORTF_BASE, GPIO_PIN_0 | GPIO_PIN_4);
//        MAP_GPIOPinTypeGPIOOutput(GPIO_PORTN_BASE, GPIO_PIN_1);
//        MAP_GPIOPinWrite(GPIO_PORTN_BASE, GPIO_PIN_1, ~GPIO_PIN_1);

FlashEEPROM_Init();//读取配置信息
 
 for(i=0;i<4;i++)
 {
 ipaddress<<=8;
 mask<<=8;
 gate<<=8; 
 
 ipaddress|=ip2Mac.ip_addr;
 mask|=ip2Mac.net_mask;
 gate|=ip2Mac.ip_gate;
 }

printf(" static ip=%d.%d.%d.%d; mask=%d.%d.%d.%d; gate=%d.%d.%d.%d desIP=%d.%d.%d.%d; desPORT=%d ",
 0xff&ipaddress>>24,0xff&ipaddress>>16,0xff&ipaddress>>8,0xff&ipaddress,
 0xff&mask>>24,0xff&mask>>16,0xff&mask>>8,0xff&mask,
 0xff&gate>>24,0xff&gate>>16,0xff&gate>>8,0xff&gate, 
 ip2Mac.dic_ip_addr[0],ip2Mac.dic_ip_addr[1],ip2Mac.dic_ip_addr[2],ip2Mac.dic_ip_addr[3],
 ip2Mac.dic_port[0]<<8|ip2Mac.dic_port[1]
 ); 
 lwIPInit(120000000, ip2Mac.mac_address, ipaddress, mask, gate, IPADDR_USE_STATIC);//静态IP
 MAP_IntPrioritySet(INT_EMAC0, 0xC0);
}
```

LWIP还没初始化完就死机了，根据这些信息可否判断问题的大致方向？
